Changing alternators in MF261

New to fixing tractors

I bought an alternator that is supposed to be a replacement for my current (original?) MF261 alternator. I've never changed an alternator before and they aren't identical so I'm a little lost. Please see picture. I have read that the red cable I marked with a * is going to be attached to B+ on the new alternator but I have NO IDEA what I am going to do with the pinkish wire. I don't see a single "prong" on the new alternator that it could slip onto. Thanks in advance!

Would like to help, I'd help if I could, but electricity is a huge mystery to me. Many things I try wind up with smoke coming out where it ain't s'posed to.
 
I checked my MF261 Alt and it is the same as your original with two wires. I would get the right one. My guess is the second wire is for internal regulator--but not sure. Good luck.
 
Still looking for help with this. I've contacted the company that I bought the alternator from and they don't know either. They are looking into it but don't guarantee they can find me an answer.

I'm starting to suspect that I'm going to need to strip the end off of the pinkish wire, replace it with one of those circle-type ends, and then attach it to D+ but that's more of a guess than anything. Does that seem right to anyone?

Thanks!
 
I was helped by a gentleman on another forum. I am posting the "answer" in case anyone else ends up with the same problem that I had.

The hot wire (red cable I marked with *) does indeed go to the B+ terminal. The pinkish wire had to have its female spade end removed and replaced with an eyelet. That eyelet was then connected to the D+.
 
I know this is an old thread, but I'm putting a new alternator on my MF261 and am having difficulty. Where did that pink wire run to.... it goes from the B+ on the alternator to where?

UPDATE:
I figured it out... it had to be routed to a indicator light, a guy told me you have to either run it to a light or a resister. It's charging now !!
